Wake it up before it wakes you up — at 2am in July.
Spring HVAC startup isn't glamorous. It's filter replacements, belt checks, coil inspections, and a cooling tower that's been sitting stagnant for five months. Skip this and you're not saving time — you're borrowing it from August.
Rooftop Units (RTUs)
Filter replacements are obvious. What gets missed: dirty evaporator coils, worn belts, and refrigerant levels that drifted over winter. A unit that turns on isn't a unit that performs.
Airflow restriction caused by dirty coils means longer run cycles, higher utility bills, and accelerated wear. It also means your tenants in Suite 204 will notice before you do.
Cooling Towers
Standing water plus five months equals bacterial growth. Legionella doesn't care about your Q2 budget. Drain, clean, and treat before startup — every time. This is not optional, and it is not a place to value-engineer.
Controls & Thermostats
Setpoints drift. Schedules get overwritten. Someone always adjusted something over winter. Recommission your building automation system before tenants start complaining about the temperature.
The Spring Startup Checklist
Replace all HVAC filters
Inspect and clean RTU evaporator and condenser coils
Check belts, bearings, and refrigerant levels
Flush, clean, and treat cooling towers
Verify thermostat schedules and setpoints
Test economizer function
Document everything for your service records
DuPage County commercial properties that skip spring startup spend the back half of summer chasing emergency HVAC calls at emergency rates. The ones that do it right are comfortable in June — and quiet.
One more thing: your rooftop is more than HVAC
Debris buildup around rooftop units restricts airflow and accelerates wear. Biological growth, dirt accumulation, and blocked drains around RTUs are a hidden efficiency tax — and a property appearance issue. If your rooftop hasn't been power washed as part of your spring service cycle, this is the week to schedule it.
